Aroused: The History Of Hormones And How They Control Just About Everything
by Randi Hutter EpsteinA guided tour through the strange science of hormones and the age-old quest to control them. Metabolism, behavior, sleep, mood swings, the immune system, fighting, fleeing, puberty, and sex: these are just a few of the things our bodies control with hormones. Armed with a healthy dose of wit and curiosity, medical journalist Randi Hutter Epstein takes us on a journey through the unusual history of these potent chemicals from a basement filled with jarred nineteenth-century brains to a twenty-first-century hormone clinic in Los Angeles. Brimming with fascinating anecdotes, illuminating new medical research, and humorous details, Aroused introduces the leading scientists who made life-changing discoveries about the hormone imbalances that ail us, as well as the charlatans who used those discoveries to peddle false remedies. Epstein exposes the humanity at the heart of hormone science with her rich cast of characters, including a 1920s doctor promoting vasectomies as a way to boost libido, a female medical student who discovered a pregnancy hormone in the 1940s, and a mother who collected pituitaries, a brain gland, from cadavers as a source of growth hormone to treat her son. Along the way, Epstein explores the functions of hormones such as leptin, oxytocin, estrogen, and testosterone, demystifying the science of endocrinology. A fascinating look at the history and science of some of medicine’s most important discoveries, Aroused reveals the shocking history of hormones through the back rooms, basements, and labs where endocrinology began.

The Arrival of the Fittest: Biology's Imaginary Futures, 1900–1935
by Jim EndersbyIn the early twentieth century, varied audiences took biology out of the hands of specialists and transformed it into mass culture, transforming our understanding of heredity in the process. In the early twentieth century communities made creative use of the new theories of heredity in circulation at the time, including the now largely forgotten mutation theory of Hugo de Vries. Science fiction writers, socialists, feminists, and utopians are among those who seized on the amazing possibilities of rapid and potentially controllable evolution. De Vries’s highly respected scientific theory only briefly captured the attention of the scientific community, but its many fans appropriated it for their own wildly imaginative ends. Writers from H.G. Wells and Edith Wharton to Charlotte Perkins Gilman, J.B.S. Haldane, and Aldous Huxley created a new kind of imaginary future, which Jim Endersby calls the biotopia. It took the ambiguous possibilities of biology—utopian and dystopian—and reimagined them in ways that still influence the public’s understanding of the life sciences. The Arrival of the Fittest recovers the fascinating, long-forgotten origins of ideas that have informed works of fiction from Brave New World to the X-Men movies, all while reflecting on the lessons—positive and negative—that this period might offer us.
The Arrival of the Fittest: Solving Evolution's Greatest Puzzle
by Andreas WagnerWe all know about natural selection and the so-called survival of the fittest, which governs how evolution preserves useful adaptations in each subsequent generation of a species. Unfortunately, random change alone could not have produced life as we know it - the maths don't add up, according to cutting-edge research by Andreas Wagner in the revolutionary field of computational biology.In the last decade, Wagner has detected the biological networks guiding the creation of innovation. His investigations of the genes of everything from bacteria to humans is rewriting our understanding of how exactly evolution works and providing insights into the origins of creativity, with lessons that can be applied far beyond genomes.In The Arrival of the Fittest, Wagner delivers a breathtaking new look at our origins, from the genes up.
Arrival of the Fittest
by Andreas Wagner"Natural selection can preserve innovations, but it cannot create them. Nature's many innovations--some uncannily perfect--call for natural principles that accelerate life's ability to innovate." Darwin's theory of natural selection explains how useful adaptations are preserved over time. But the biggest mystery about evolution eluded him. As genetics pioneer Hugo de Vries put it, "natural selection may explain the survival of the fittest, but it cannot explain the arrival of the fittest." Can random mutations over a mere 3.8 billion years really be responsible for wings, eyeballs, knees, camouflage, lactose digestion, photosynthesis, and the rest of nature's creative marvels? And if the answer is no, what is the mechanism that explains evolution's speed and efficiency? In Arrival of the Fittest, renowned evolutionary biologist Andreas Wagner draws on over fifteen years of research to present the missing piece in Darwin's theory. Using experimental and computational technologies that were heretofore unimagined, he has found that adaptations are not just driven by chance, but by a set of laws that allow nature to discover new molecules and mechanisms in a fraction of the time that random variation would take. Consider the Arctic cod, a fish that lives and thrives within six degrees of the North Pole, in waters that regularly fall below 0 degrees. At that temperature, the internal fluids of most organisms turn into ice crystals. And yet, the arctic cod survives by producing proteins that lower the freezing temperature of its body fluids, much like antifreeze does for a car's engine coolant. The invention of those proteins is an archetypal example of nature's enormous powers of creativity. Meticulously researched, carefully argued, evocatively written, and full of fascinating examples from the animal kingdom, Arrival of the Fittest offers up the final puzzle piece in the mystery of life's rich diversity.
The Arrow Of Time
by Roger Highfield Dr Peter CoveneyIn our century, the subject of time has become an area of serious inquiry for science. Theories that contain time as a simple quantity form the basis of our understanding of many scientific disciplines, yet the debate rages on: why does there seem to be a direction to time, an arrow of time pointing from past to future?In this authoritative and accessible Sunday Times bestseller, physical chemist Dr Peter Coveney and award-winning science journalist Dr Roger Highfield demonstrate that the common sense view of time agrees with the most advanced scientific theory. Time does in fact move like an arrow, shooting forward into what is genuinely unknown, leaving the past immutably behind. The authors make their case by exploring three centuries of science, offering bold reinterpretations of Newton’s mechanics, Einstein’s special and general theories of relativity, quantum mechanics, and advancing the insights of chaos theory. In their voyage through science the authors link apparently irreconcilable subjects, from Einstein’s obsession with causality to chaos theory, from Marvell’s winged chariot to that Monday morning feeling.Finally, drawing together the various interpretations of time, they describe a novel way to give it a sense of direction. And they call for a new fundamental theory to take account of the Arrow of Time.Foreword by Ilya Prigogine, Nobel laureate.
Arrow Pushing in Inorganic Chemistry
by Steffen Berg Abhik GhoshInvolved as it is with 95% of the periodic table, inorganic chemistry is one of the foundational subjects of scientific study. Inorganic catalysts are used in crucial industrial processes and the field, to a significant extent, also forms the basis of nanotechnology. Unfortunately, the subject is not a popular one for undergraduates. This book aims to take a step to change this state of affairs by presenting a mechanistic, logical introduction to the subject. Organic teaching places heavy emphasis on reaction mechanisms - "arrow-pushing" - and the authors of this book have found that a mechanistic approach works just as well for elementary inorganic chemistry. As opposed to listening to formal lectures or learning the material by heart, by teaching students to recognize common inorganic species as electrophiles and nucleophiles, coupled with organic-style arrow-pushing, this book serves as a gentle and stimulating introduction to inorganic chemistry, providing students with the knowledge and opportunity to solve inorganic reaction mechanisms. * The first book to apply the arrow-pushing method to inorganic chemistry teaching * With the reaction mechanisms approach ("arrow-pushing"), students will no longer have to rely on memorization as a device for learning this subject, but will instead have a logical foundation for this area of study * Teaches students to recognize common inorganic species as electrophiles and nucleophiles, coupled with organic-style arrow-pushing * Provides a degree of integration with what students learn in organic chemistry, facilitating learning of this subject * Serves as an invaluable companion to any introductory inorganic chemistry textbook

The Arrows of Time
by Laura Mersini-Houghton Rudy VaasThe concept of time has fascinated humanity throughout recorded history, and it remains one of the biggest mysteries in science and philosophy. Time is clearly one of the fundamental building blocks of the universe and thus a deeper understanding of nature at a fundamental level also demands a comprehension of time. Furthermore, the origins of the universe are closely intertwined with the puzzle of time: Did time emerge at the Big Bang? Why does the arrow of time 'conspire' with the order of the initial state of the universe? This book addresses many of the most important questions about time: What is time, and is it fundamental or emergent? Why is there such an arrow of time, closely related to the initial state of the universe, and why do the cosmic, thermodynamic and other arrows agree? These issues are discussed here by leading experts, and each offers a new perspective on the debate. Their contributions delve into the most difficult research topic in physics, also describing the latest cutting edge research on the subject. The book also offers readers a comparison between the different outlooks of philosophy, physics and cosmology on the puzzle of time. This volume is intended to be useful for research purposes, but most chapters are also accessible to a more general audience of scientifically educated readers looking for deeper insights.

Arsenic in Drinking Water
by National Research CouncilThe U.S. Environmental Protection Agency (EPA) has been considering a more stringent regulation of arsenic in water. A significant reduction in the maximum contaminant level (MCL) could increase compliance costs for water utilities. This book discusses the adequacy of the current EPA MCL for protecting human health in the context of stated EPA policy and provides an unbiased scientific basis for deriving the arsenic standard for drinking water and surface water.Arsenic in Drinking Water evaluates epidemiological data on the carcinogenic and noncarcinogenic health effects of arsenic exposure of Taiwanese populations and compares those effects with the effects of arsenic exposure demonstrated in other countries—including the United States.The book also reviews data on toxicokinetics, metabolism, and mechanism and mode of action of arsenic to ascertain how these data could assist in assessing human health risks from arsenic exposures. This volume recommends specific changes to improve the toxicity analyses and risk characterization. The implications of the changes for EPA’s current MCL for arsenic are also described.
Arsenic in Drinking Water and Food
by Sudhakar SrivastavaArsenic contamination poses a major environmental problem, especially in Southeast Asian countries like Bangladesh and India. Threatening the health of millions of people due to arsenic’s toxicity and carcinogenicity, the major routes of arsenic exposure for humans are either through drinking water or crops. Rice is the crop most affected by arsenic owing to its cultivation in major arsenic contaminated areas, biogeochemical factors in the soil during rice growth, and specific features of rice that enable it take up more arsenic than other crop plants. This book addresses the problem of arsenic by pursuing a holistic approach. It presents the status quo in different parts of the world (North and South America, Europe, Asia, etc.) and provides essential information on food-related arsenic exposure risks for humans, and possible preventive and curative measures for tackling arsenic poisoning. It covers the arsenic contamination status of rice, rice-based products, other vegetables, fishes, mushrooms, and other foods, with a special focus on rice-arsenic interactions. The mechanisms of arsenic uptake, translocation and distribution in plants and grains are also explained. In closing, the book reviews a variety of prospective agronomic and biotechnological solutions to the problem of arsenic accumulation in rice grains. The book is intended for a broad audience including researchers, scientists, and readers with diverse backgrounds including agriculture, environmental science, food science, environmental management, and human health. It can also be used as an important reference guide for undergraduate and graduate students, university faculties, and environmentalists.
